Isn't the point of ESM is to trick tha map sensor to NOT see the boost.

NFRen

Thats what I was thinking.

Another question that may be answered....How do you test the diverter valve, and how to tell if I've got the correct end in the Intake elbow..I have an aftercooler.

If you want to vent to the atmosphere, do you have to put it on the aftercooler and plug up the whole in the SC intake??

Thanks
